Massive small bowel resection (SBR) and vancomycin treatment alter the fecal microbiome. (A) 16s rRNA sequencing of feces prior to small bowel resection (baseline). (B) Fecal microbiome three weeks after resection (n=5). (C) Fecal microbiome three weeks after resection and oral vancomycin treatment (n=7). *p<0.05 when comparing baseline to 3 weeks after SBR, ** p<0.01 when comparing baseline to 3 weeks after SBR, *** The only common major constituent when comparing 3 weeks after SBR to 3 weeks after SBR + vancomycin. (p<0.001) All other major constituents of the SBR+vancomycin microbiome were not significant constituents in the mice 3 weeks after SBR alone. (D) Microbial constituents of the fecal microbiome at the phylum level from mice at baseline 3 weeks after massive SBR, and 3 weeks after massive SBR plus oral vancomycin treatment. *p<0.01 when comparing baseline to control for Proteobacteria, # p<0.05 when comparing baseline to control for Verrucomicrobia, ** p<0.01 when comparing control and vancomycin treated at 3 weeks for all 5 phyla.
